YARN-PRINTING MACHINE.

Application filed March 17, 1920. Serial N0.'366,686.

To aZZ 20/20/11. it may concern:

Be it known that l.- Anriucn HANSON, Six,

a citizen of the United States residing at Yonkers, in the county of Vfestchester and State of New York have invented certain new and useful Improvements in Yarn- Printing Machines, of which the following is a specification reference being had therein to the accompanying drawing;

This invention relates to improvements in machines for applying coloring matter to yarn previous to the weaving operation. in a machine oi this class, the dye or color fluid is applied to the yarn while the latter is wrapped around a drum. In general, the apparatus comprises a framework supporting a car reciprocated by a power mechanism beneath and longitudinally of the axis of the drum. The car carries a box holding an amount of the coloring fluid, and also supports a printing: wheel whose periphery, over one short are, is constantly dipping into coloring fluid, and, over another short are, is pressing against the yarn wound on the drum, thus applying the coloring matter.

One of the objects of the invention is to pro ide a novel scraping device and a novel mounting therefor for regulating the amount of coloring matter which is carried upward so by the periphery of the color wheel after it is immersed in the fluid.

Another object is to provide a novel means and a novel mounting thereii'or to prevent the liquid in the color box from being thrown up over the end of the box when the car is suddenly stopped or started at the end of its path. v

Another ,object is to provide means to automatically keep the liquid in the box at an approximately predetermined level.

Another object is to provide color distribmin and checking devices of such character the the colm-carryingi be can be conslri'icicd oi much cheaper material and yet be non-c(' rrosive and refractory relatively to the compo"; cuts of the color fluid.

Fig. 7 is a view, partly in elevation, partly in section, of the stationary tank and its attachments, taken on the line 775 of Fig. 6.

Fig. 8 is a detail showing the valve and its actuating arm.

A main frame is indicated ,by A, upon which is mounted a yarn drum B. With the latter are combined feeding and controlling devices, indicated by C. These parts of the apparatus may be of any well known or preferred character.

They are in common use and impart stepby-step movements to the drum in timed relation with the movements of the reciprocating devices which impart the color to the yarn on the drum in the usual way.

The frame of the machine is provided with horizontal track rails 1, 1 on which travels a wheeled carriage 2. 3 is a cable passing around the sheaves 4c and 5 and having its ends fastened to the carriage 2 at 30, of Elly means of suitable power devices attached to one or both of the sheave wheels; the carriage is moved back and forth on the tracks 1 beneath the yarn drum B and longitudinally on its axis. Standards, 7, 7 together with suitable cross bars and bracing devices support the drum B and the actuating mechanism associated therewith.

8 is the box. for holding the coloring material. It is detachah intmnted upon the bed 9 or" the car orcarriag c 2. 1%) is the color wheel mounted on the shaft 11. the latter being removably held in berings 12 on the downw" willy yielding: spring-held frame 13. 85. 35 are rubbers fil'ltlll'o.,l to

press against the yarn after it has been colcred. 36. 36 indicate the devices b which the rubbers are moved to and fron'i their operative positions.

As the parts cescrioed above are well known to those acquainted i the art and form no part of the present invention, aidetaile d description is not necessary.

At-each end of the box 8 there is adevice- 37 to insure a unit'orinquantity of coloring material at all points around the periphery ofwheel 10, and to also insure that none of the fluid shall be carried upward and out of the box, either because of sudden stoppage or starting of the latter or because oi? the rotation of the wheel. Each of the devices 21)? comprises two relatively movable clementsilS and 89. The element 39 is a plate-like part adjacent the end wall. of the box and formed with two curved baii'le plates 1 141:, one on each side of the color wheel 10. The width of each of these plates 1a is slightly less than the distance between the side wall of the box'and the adjacent side face of the color wheel. Each of these elemeins 39 is formed with a central portion curved upwardly and outwardly to supplement the baffle function of the parts 14-, l hand they occupy a predetermined fixed position with respect to the color wheel; they are held against lateral displacement by the side walls of the box 8 and against longitudinal displacement by vertical ribs 16 positioned one on each side, and at each end of the box. The baffle plates 14 are positioned with their concave surfaces facing downward and serve to catch all the color fluid which may be thrown upward against them, and, because of their peculiar conformation, they immediately return the fluid toward the bottom of the box.

l7, 17 are two upward projecting lugs formed integral with the element 39. These lugs are designed to hold the element 38, to

, be described, and are provided with the transverse hinge apertures 18.

Each element 38 comprises a scraper device 40 adapted to engage with the peripheral surface of the color wheel at points approximately equidistant from its central vertical line, and a transverse hinge formed of pins 19. The hinge pins are fitted in the apertures 18 in the aforesaid lugs 17. At the end which bears against the color wheel, each scraper is formed with a slot 40' approximating in width that of the peripheral tongue 8 of the color wheel. The

depth of the slot is somewhat greater than the radial depth of this peripheral surface of the tongue and the bottom of the slot. The bearing edges of the scraper device rest upon and scrape the shoulders 8 of the color wheel 8 and serve to remove therefrom the fluid which adheres to these shoulders and to the side faces of the tongue 8. The operative part of the scraper device 40 is made of comparatively heavy material, and gravity alone is relied upon to hold it in constant contact with the said shoulders and sides. The length of the pins 19 such that when the lugs 18 are lifted above the top edges of the box, the pins can be inserted into the lugs 17 by first slipping one pin into the aperture 18 in its lug 17, and then continuing this slipping far enough to permit the opposite pin 19 to be brought to align with the aperture in its lug, after which it can he lipped in the opposite direction into the latter. Then the device 37 can, as an entirety, he slipped downward into the box 8 to its operative position; and after the lugs 17 have descended below the top edges oi the box walls, the latter prevent the hinge pins 19 troin slipping laterally and hold the scraper 38 in its proper central position.

is a float of any suitable buoyant material. 24c is an upright secured to it and pivoted at 25 to a lever 26. The latter is, in turn, pivoted at 27 to a bracket 27, which is secured by a clamp 27 to the side wall of the color box 8. The outer end 28 of the trip lever 26 is adapted, under'certain circumstances, to engage with a valve-operating lever 29, and thereby open or close Valve 30 to which the level 29 is connected. 32 is a tank adapted to hold a considerable amount of coloring material, and into the bottom of this tank is fitted the duct carrying said valve 30.

The tank is held by any suitable means at one end of the framework A which sup ports the printing machine, as an entirety, and is so positioned that when the valve 30 is opened by the lever 29 and tripper 28, the liquid flowing through the valve duct will be discharged into one end of the color box 8. The valve 80 is held normally closed by aspiral spring 34: so that when the car 2 is moving away from the tank 32 and the end of the lever 28 is receding from the valve tripper 28, the valve will be immediately clpsed and improper discharge of coloring matter will be avoided, after the end of the box has passed from beneath the valve aperture 33.

The heat 23, valve 30, and the intermediate actuating devices are so adjusted and related as to maintain, constantly, in the box the amount of fluid which is proper in relation to the baffle plates 14!: and the scraper 40. The level of the fluid C(fi'ltlOllQCl by the float should be such that, on the one hand, the color wheel will always have a section of its periphery immersed to the predetermined depth, and, on the other hand, the quantity of the fluid picked up by the wheel will not be too great to be properly controlled by the scraper 4-0 and the baffles 14-. And, again,'tlie parts should be so adjusted that the quantity supplied from the station ary tank 32 and maintained constantly in the box will not he so great as to result in the tin-owing or spurting oi fluid upward at times when the box is stopped in its move ment in one direction and then quickly reversed.

The color-carrying and printing devices of earlier designs have been supplied intermitt-ingly by manually pouring the fluid from portable vessels, It the pouring was eltected while the box and carriage were in there was, inevitably, a slopping from the purpose.

heretofore available.

box of the color fluid. It the box and carriage be stopped to permit the supplying of more fluid there was much loss of time incident to the stopping and starting again of the apparatus.

All of these disadvantages are obviated when using my mechanism. The automaticall acting parts are so adjusted, as above stated, that the material in the box is accurately regulated, and evenly distributed, and the baiiie and scraping meansare so related to the Supply devices that all the parts can be maintained in a practically perfectly clean condition.

The box is imperi'orate, not having any apertures through its walls to receive the hinge pins of the scraper 40, or for any other On. the other hand, the several parts, it will be seen, are so made and related that they can be separated or can be put into position, and there held operatively, without requiring the forming of any apertures through the box walls. The scraping and battling device 37, regardless of its being made in several parts, can be detached, or inserted into 1 position by a vertical slipping movement without requiring the removal or insertion of pins, screws, or the like. And this enables me to construct the box of materials that were not The color material. used contains components which prohibit the use of cheap metals if there are any points where the metal is exposed to contact with such components, rusting or the like being caused wherever there is such contact. And such exposure of metal necessarily occurs whereperi'orations are formed in the walls for the seating of hinges,pivots, pins, screws or the like. Hence these coloring boxes have heretofore been made of nonmetallic substances such as hard ruhli'er, which resist the action of these components;

but the use of rubber largely increases the expense. By constructing and relating the scraping and checking devices in such way as to avoid the forming oi? apertures or per- "lorations in the walls of the box, I am en'- aided remake it of cheap metal as I have to merely cover it at all fluid contacting points with a suriiace ot refractory, earthy or the like material.

walls to rec'eive hinges, pivot rods, orscrews;

and if such walls were made of metal, rustthe boxes cleaning, both for removing foreign materials that accumulate, and also because of the necessity of changing from one coloring matter to another. And such cleansing can be readily effected because of the smooth vitreous enameled surfaces formed on the metal Walls.

The enameling can be readily applied in such way that although the scraper and the scraper supports are largely in contact with the wallsot the box, the metal surfaces be neath the enamel are protected from exposure through cracking or wearing away of the enamel, and the metal at the lower end parts of the slots which serve as bearings for the shaft 11, can be similarly protected.
